Quantitative Morphology of High-Redshift Galaxies Using GALEX Ultraviolet Images of Nearby Galaxies [PDF]
Journal of Astronomy and Space Sciences, 2017 We present simulations of the optical-band images of high-redshift galaxies utilizing 845 near-ultraviolet (NUV) images of nearby galaxies obtained through the Galaxy Evolution Explorer (GALEX). We compute the concentration (C), asymmetry (A), Gini (G),

The Astrophysical Journal, 2023 A key question in galaxy evolution has been the importance of the apparent “clumpiness” of high-redshift galaxies. Until now, this property has been primarily investigated in rest-frame UV, limiting our understanding of their relevance.

The Astrophysical Journal, 2023 We examine the wavelength dependence of radial light profiles based on Sérsic index n measurements of 1067 galaxies with M _* ≥ 10 ^9.5 M _⊙ and in the redshift range 0.5 < z < 3. The sample and rest-frame optical light profiles are drawn from the Cosmic

Galaxy Phase-Space Density Data Preclude That Bose–Einstein Condensate Be the Total Dark Matter
Universe, 2022 Ultralight scalars with a typical mass of the order m∼10−22 eV and light scalars forming a Bose–Einstein condensate (BEC) exhibit a Jeans length in the kpc scale and were therefore proposed as dark matter (DM) candidates.

The photometric structure of the inner Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 1997 The light distribution in the inner few kiloparsecs of the Milky Way is recovered non-parametrically from a dust-corrected near-infrared COBE/DIRBE surface brightness map of the inner Galaxy. The best fits to the photometry are obtained when the Sun is assumed to lie $\sim14\pm4\pc$ below the plane.

Spirality: A Novel Way to Measure Spiral Arm Pitch Angle
Galaxies, 2022 We present the MATLAB code Spirality, a novel method for measuring spiral arm pitch angles by fitting galaxy images to spiral templates of known pitch. Computation time is typically on the order of 2 min per galaxy, assuming 8 GB of working memory.

RR Lyrae Variables as Tracers of the Galactic Bulge Kinematic Structure
Universe, 2022 RR Lyrae stars are recognized as some of the oldest stars in the Universe. In addition, they are some of the few old celestial objects for which distances can be reliably inferred.
